Seward Park, Seattle, WA
Road cycling event
The longest days of the year mean the longest twilight battles at Seward Park's Thursday night series.
With the summer solstice just days away, the Seward Park Thursday Night Cycling Series takes advantage of maximal daylight for another round of fast-paced evening racing. The park's forested loop offers a unique blend of shade and speed. This weekly series remains one of the most accessible entry points to competitive cycling in Seattle, with a welcoming community and well-run fields that keep riders coming back all season long.
